1 y = 3 x + 2
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = 3.000 x + 2
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 3
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal m1*m2=-1
\n" ); document.write( "The slope of the required line will be -1/3
\n" ); document.write( "
\n" ); document.write( "m= - 1/3 ,point ( 1 , -1 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-1 = -1/3 + b
\n" ); document.write( "b= -2/3
\n" ); document.write( "
\n" ); document.write( "m= - 1/3
\n" ); document.write( "The required equation is y = - 1/ 3 x - 2/ 3 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "----------------\r
\n" ); document.write( "\n" ); document.write( "1 y = 2/3 x -4
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = 0.667 x + -4
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 2/3
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -1.5

\n" ); document.write( "m= -3/2 ,point ( 5 , 0 )
